Light-matter interaction between templated molecular layers and surface lattice resonances

Roland Schäfer, Manuel Neubauer, Klaus Meerholz +1

We couple a templated layer of merocyanine molecules with surface lattice resonances in a plasmonic grating. The templating of the molecular layer is achieved using a layer of alig…

Tunable photogating in a molecular aggregate coupled graphene phototransistor

Abhinav Raina, Maurizio Sanfilippo, Chang-Ki Moon +4

We present a graphene photodetector coupled to a layer of aggregated organic semiconductor. A graphene phototransistor is covered with a thin film of merocyanine molecules. The agg…

Polarization-controlled strong light-matter interaction with templated molecular aggregates

Roland Schäfer, Philipp Weitkamp, Otgonbayar Erdene-Ochir +2

We demonstrate strong light-matter interaction for a layer of templated merocyanine molecules in a planar microcavity. Using a single layer of graphene nanoribbons as a templating…

Influencing Optical and Charge Transport Properties by Controlling the Molecular Interactions of Merocyanine Thin Films

Lukas Böhner, Philipp Weitkamp, Thorsten Limböck +8

In organic semiconductors charge transport typically takes place via slow hopping processes. Molecular aggregation can lead to enhanced exciton and charge transport through couplin…

Computation of the spatial distribution of charge-carrier density in disordered media

Alexey V. Nenashev, Florian Gebhard, Klaus Meerholz +1

The space- and temperature-dependent electron distribution determines optoelectronic properties of disordered semiconductors. It is a challenging task to get access to $n(…

Qubits, entangled states, and quantum gates realized on a set of classical pendulums

Alexey V. Nenashev, Florian Gebhard, Klaus Meerholz +1

Here we show that the concepts behind such terms as entanglement, qubits, quantum gates, quantum error corrections, unitary time evolution etc., which are usually ascribed to quant…

Parametrization of the Charge-Carrier Mobility in Organic Disordered Semiconductors. APAE against EGDM

S. D. Baranovskii, A. V. Nenashev, D. Hertel +2

An appropriately parameterized compact analytical equation (APAE) is suggested to account for charge carrier mobility in organic disordered semiconductors (ODSs). This equation cor…
